洋葱抽薹与未抽薹植株生理生化特性对比研究

以红太阳（Red Creole）洋葱为试材，研究抽薹与未抽薹植株生理生化特性的差异。结果表明：同一时间，抽薹植株与未抽薹植株存在一定的差异；鳞茎形成期，未抽薹植株游离氨基酸与可溶性蛋白质含量较高，抽薹植株可溶性糖含量、C/N值及POD活性较高。抽薹期，抽薹植株游离氨基酸与可溶性蛋白质含量较高，未抽薹植株可溶性糖含量、C/N值及POD活性较高。这可能是不同处理植株发育进程不同的原因。电泳结果显示，二者蛋白质组分存在一定差异。

Studies on the Difference of Bolting and Unbolting Onions on the Physiological and Biochemical Characteristics

With Red Creole as experimental materials, the effects of physiological and biochemical characteristics by different treatments and developmental stages were studied. The results showed that: boltings and unboltings were different in the same period. The soluble protein and free amino acid were higher in unbolting onions, the soluble sugar, C/N and POD activity were higher in bolting onions on bulbing period. Else, the soluble protein and free amino acid were higher in bolting onions, the soluble sugar, C/N and POD activity were higher in unbolting onions on bolting period. Maybe it was caused by different growth periods. SDS-PAGE indicated that protein was different with the two treatments.
